KIS Sivar, Vega Sector circa 2654.

The first Sivar-class dreadnoughts entered service before the beginning of the Terran-Kilrathi conflict. Notoriously fast for a battleship, the Sivar-class could deliver a large amount of men and munitions into battle quickly. For that reason, Sivars served as the centerpiece of nearly every Kilrathi task force through the end of the Vega Campaign. Over 700 were produced. The Terran Confederation managed to capture several original Sivar-class ships, including an unarmed example in drydock during the Epsilon Initiative. All eight noble clans build and staff Sivar-class ships.

The notable spinoff of the Sivar-class design is the Sivar-class ship which destroyed the Goddard colony. Armed with an experimental Proton Accelerator Gun, the Sivar and her support fleet crossed the border and completely destroyed the human colony. The TCS Tiger's Claw pursued the ship and her fleet, eliminating them all in a daring act of vengeance. During a series of secret missions, four Bengal carrier groups attacked and destroyed the shipyards which produced the weapon.

A third Sivar-spinoff, based on the hull of the colony-destroying weapon, served as a pocket carrier in limited roles.
